Question

• Create a new project called Lab05b. Keep the main file named main.
• Write a function readAndPrint, and power with parameters noted below in the Functions.h file.

//Your Last Name

#ifndef FUNCTIONS_H

#define FUNCTIONS_H

#include <fstream>

#include <iostream>

#include <string>

using namespace std;

/*reads from a file

and prints every item to the screen*/

// file contains sets of

//int

//string

//Don't forget to use infile.ignore() between << and getline

//ifstream must be passed by reference

void readAndPrint(ifstream &infile);

//uses a for loop to return the base to the exponent

//e.g. 2^4 = 16

// this fuction should read data.txt file

long power(long base, long exponent);

#endif

• You should place the function prototypes in a file called Functions.h The function prototype has a semi-colon at the end.
• Then you should implement in a file called Functions.cpp
• Finally, declare the infile, and call the readAndPrint function. Then look at the power of 2^3 and 10 ^ 4

• Create a file named data.txt that has the following information.

1

Alpha

2

Beta

3

Gamma

• Your functions.cpp AND your lastnamefirstLab05b.cpp should #include “Functions.h”.
• Remember that you should not #include.cpp files!
• Implementation detail 4: compile and run with:
